Can anyone supply me with instructions how to remove my mirror plastic covers so I can replace them with chrome covers?

 

drive down a one way street in the wrong direction

never fails

 

Here's a basic idea of how it's done.
I used a similar walkthrough to do mine, but it's pretty much the same thing.

Pop the mirror off, take out a few screws, undo a few clips and then put back together in reverse.

HERE'S A LINK

 

Sorry
I have a 1998 model A4 B5 model so I assume link with instructions should be the same!
